Level is equipped with first crossbar, and one end of the first crossbar is fixedly mounted on Crashworthy plate close to the centre of column side, and described the
The by-level of the other end of one cross bar is equipped with mounting groove, is rotatablely installed there are two connecting rod by shaft in the mounting groove,
Above and below two through grooves in be fitted with second crossbar, one end difference of two connecting rods far from mounting groove
Be rotatablely connected by shaft close to one end of mounting groove with two second crossbars, two second crossbars far from mounting groove one
End is vertical and is installed with baffle, and the centres of two connecting rods is rotatably connected to supporting rod by shaft, two
The horizontally disposed and one end far from connecting rod of the supporting rod is respectively and fixedly installed on column.
Preferably, the top center of the clump is equipped with groove vertically, and the bottom of the column is inserted into groove, institute
It states the surrounding level of the lower part of column and is installed with mounting ear, be all provided on each mounting ear and at the top of clump
There is the corresponding mounting hole in position, screw is fitted with jointly in each pair of mounting hole.
Preferably, the every piece of side of the baffle far from column is equipped with reflecting piece.
Preferably, it is equipped with sliding slot on two connecting rods one end close to each other, the shaft in the mounting groove point
Not Chuan Guo sliding slot connect with connecting rod.
The utility model proposes a kind of new road science of bridge building protective device, advantageous effect is：This practicality is new
Type is simple in structure, and when Vehicular impact protective fence, Crashworthy plate deformation absorbs part energy, while baffle is produced to the direction of vehicle
Raw thrust, further buffers, compared with traditional bridge guardrail, energy-absorbing function is apparent, strong applicability.
Description of the drawings
Fig. 1 be the utility model proposes a kind of new road science of bridge building protective device structural schematic diagram.
In figure：Clump 1, mounting hole 2, through groove 3, first crossbar 4, Crashworthy plate 5, baffle 6, second crossbar 7, column 8, branch
Strut 9, connecting rod 10, mounting groove 11, mounting ear 12, screw 13, groove 14, sliding slot 15.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1, a kind of new road science of bridge building protective device, including spaced multiple clumps 1, each
The top center of clump 1 is vertical and is installed with column 8, and being equipped with section jointly among the side of each column 8 is
Arc-shaped Crashworthy plate 5, the deformation of Crashworthy plate 5 can absorb the impact energy of a part, play buffering effect.
On each column 8 from top to bottom uniformly and level is set there are three through groove 3, horizontal in intermediate through groove 3 to be equipped with first
One end of cross bar 4, first crossbar 4 is fixedly mounted on Crashworthy plate 5 close to the centre of 8 side of column, when Crashworthy plate 5 is knocked
Deformation pushes first crossbar 4 to move.
The centre of two connecting rods 10 is rotatably connected to supporting rod 9 by shaft, and two supporting rods 9 are horizontally disposed and remote
One end from connecting rod 10 is respectively and fixedly installed on column 8, and connecting rod 10 is using the end of supporting rod 9 as fulcrum, Ke Yijin
Row rotation drives the end of connecting rod 10 using supporting rod 9 to be rotated as fulcrum when first crossbar 4 moves.
The by-level of the other end of first crossbar 4 is equipped with mounting groove 11, is rotatablely equipped with by shaft in mounting groove 11
Two connecting rods 10, above and below two through grooves 3 in be fitted with second crossbar 7, two connecting rods 10 are far from mounting groove
11 one end is rotatablely connected close to one end of mounting groove 11 by shaft with two second crossbars 7 respectively, two 10 phases of connecting rod
When in playing the role of two levers.
Two one end of second crossbar 7 far from mounting groove 11 are vertical and are installed with baffle 6, when first crossbar 4 pushes away
When one end of the dynamic connecting rod 10 being attached thereto is moved to the direction far from column 8, the other end of connecting rod 10 is to close to column 8
Direction movement, push baffle 6 to the vehicle of shock generate thrust.
The top center of clump 1 is equipped with groove 14 vertically, and the bottom of column 8 is inserted into groove 14, the lower part of column 8
Surrounding it is horizontal and be installed with mounting ear 12, it is corresponding with the top of clump 1 to be equipped with position on each mounting ear 12
Mounting hole 2, be fitted with screw 13 jointly in each pair of mounting hole 2, facilitate and installed.
It is equipped with reflecting piece per side of the block baffle 6 far from column 8, for warning passing vehicle.
Two connecting rods 10 are equipped with sliding slot 15 on one end close to each other, and the shaft in mounting groove 11 is each passed through sliding slot
15 connect with connecting rod 10, when ensureing that first crossbar 4 moves horizontally, connecting rod 10 can smoothly be driven to move.
When in use, when there is Vehicular impact to Crashworthy plate 5, Crashworthy plate 5 deforms upon absorption one to the utility model
Partial energy, while first crossbar 4 is pushed, first crossbar 4 drives connecting rod 10 close to one end of mounting groove 11 to far from vertical
The direction of column 8 moves, and connecting rod 10 is used as lever, the other end to push baffle 6 to be pushed away to the generation of the vehicle of shock by second crossbar 7
